With the recent publication of Apple’s App Store review guidelines, one of my favourite quotes is definitely “We have over 250,000 apps in the App Store. We don’t need any more Fart apps. If your app doesn’t do something useful or provide some form of lasting entertainment, it may not be accepted.” If only they really enforced it… Anyway with the plentiful supply of various camera apps already on the Store it would seem a new contender to the genre should be something original, especially considering the above-mentioned guideline. And Camera illusion actually is!
